The migration of Sb in fine-grained and coarse-grained samples was studied at 930 to 1150C by using 125Sb autoradiography and sectioning techniques. The results could be described by:

D (cm2/s) = 1.35 x 101 exp[-3.9(eV)/kT]

It was considered that an important role was played by dislocation formation during diffusion annealing.
